Demand Response Technology Evaluation of AutoDR Programmable Communicating Thermostats

The purpose of this study was to conduct field measurements to evaluate the Demand Response (DR) capabilities of Programmable Communicating Thermostats (PCTs) leveraging Open Automated Demand Response (OpenADR). This evaluation specifically relates to packaged rooftop Heating Ventilation and Air Conditioning (HVAC) units at fast food restaurants, a market segment generally outside of the OpenADR scope. This project examined a low-cost entry for this market segment to explore the potential demand savings. The DR study was managed by Southern California Edison’s (SCE) Design and Engineering Services Group. The main objectives of the project were to: 1.Determine whether the PCTs reliably received the DR signal 2. Determine whether the PCTs reduced Air Conditioning (AC) demand when receiving a DR signal 3. Determine how much AC demand was dropped for each setting tested
